SCHEDULING OF COMPUTATIONAL PROCESSES

A method of a quality of service scheduler for scheduling the execution of a first and second linked atomic computational process on a heterogenous processing system including a first and a second processor of a different type. The method includes: receiving, from an application, a request to compute a job, the job including first and second linked atomic computational processes, and being associated with a quality of service requirement; determining, based on a register of elements of the heterogenous processing system, one or more tentative execution plans of the first and second linked atomic computational processes on the elements; selecting, as an intended execution plan, an execution plan of the first and second linked atomic computational processes, wherein the intended execution plan is capable of meeting the quality of service requirement provided by the application; and scheduling the execution of the first and second linked atomic computational processes.
